Filter frame connection structure of air conditioner {COUPLING STRUCTURE OF FILTER FRAME FOR AIR HANDLING UNIT}

The present invention relates to a connection structure of a filter frame installed at an air inlet of an air conditioner system for supplying cooling and cooling air to a room, and fixedly supporting a filter for filtering dust or dust in the air. The filter frame made by the prefabricated structure is simply to form a rectangular frame.

Generally, the air conditioner filter frame is made of light metal, and is used. In this case, the metal plate is drawn to a predetermined size and subjected to a series of metal plate working processes such as bending and punching to achieve a desired shape. In assembling the next completed frame members, a complete filter frame having a rectangular shape that can be fixed to the filter by separately using a connecting member or by bending or riveting is completed.

In addition, when the filter frame is made of wood and is used, the wood is cut and processed into a designed shape to form a first completed frame member, and in assembling such frames, a filter is used by bonding means or nailing with an adhesive. We have completed the complete filter frame of square shape to fix.

However, in the conventional frame fabrication structure described above, in the case of using a metal, a series of work steps to achieve the desired shape is not only cumbersome, but also requires manufacturing a plurality of molds for each process. It also cost a lot of production. In addition, the assembly process to form a complete filter frame requires a separate connecting member or a separate assembly process by a mold and a tool, so that the production time and production cost is high, and the production and assembly can be performed only at a certain place, that is, a production plant. Since there is no choice but to increase the volume during transportation, there is a problem in that the burden of transportation costs is increased.

On the other hand, when manufactured from wood, not only is the production process difficult, but also the production cost is increased due to the high cost of materials, which is inefficient. Due to the difference in the degree of durability is not uniform, it takes a lot of time until the adhesive is completely solidified, there is a problem that mass production is difficult, such as increased production cost.

Accordingly, the present invention was created to solve the above problems, the object of the present invention is to produce a filter frame member made of synthetic resin material by injection molding to reduce the time required for production and extreme ease in production It provides a filter frame that can be easily achieved by assembling a number of filter frame members without tools, and also provides a filter frame free of waste by allowing the separated filter frame to be separated and crushed to be reproduced or incinerated. It is.

The present invention for achieving the above object is to produce a filter frame member having a cross-section of the "c" shape made of a synthetic resin material, one side end is formed with a frame seat having a symmetrical inclined protrusion, the other end is a symmetrical coupling hole And four filter frame members formed by integrally mounting mounting guides to easily assemble the filter, and at the same time, a plurality of pedestal inserts are provided on one open side of the filter frame member to fix the filter frame. It is configured to insert a filter support to prevent the opening and deformation of the filter.
